According to the gravity disturbing potential coefficients of 2~36 orders of Rapp 81 Earth's gravity field model,and by using two spherical harmonics filtering methods-g/N method and amplitude spectrum method,a detail investigation has been made on the mass distribution of gravity anomalous sources in China and its environs. The results reveal the inner relation and laws between the gravity disturbing potential coefficients and the mass distribution of gravity anomalous sources and provide people with new...
